To explain this, let us recall some background.
While impressive in many ways, the precise relationship between random tensor networks and AdS/CFT is not yet fully understood.
So far, the best understanding is that tensor networks resemble so-called fixed-area states, which have approximately flat Rényi spectra just like random tensor networks [1]}, [2]}.
This matching is quite good; both fixed-area states and random tensor networks have exactly the same non-perturbative corrections to the Rényi entropies [3]}.
